I'm in the same boat, my appointment is Monday, although I don't really know how it's going to work exactly, she is a gender therapist, and transgender services navigator for the place that I picked, it's a very new coalition of Doctors, surgeons, and therapists who cater to transgender patients. If it takes off maybe CT will be another Thailand, one can only hope...
Still even though I don't own any female clothes, have a beard, and need to lose a bunch of weight, the fact is I'd like to start changing my body, I'll deal with telling people as they need to know, given that my goal is not just to pass as female in the next 3 years, but to also lose the ability to pass as male I feel like they won't find it hard to believe I'm sincere at the very least.
Almost forgot, just be you, even if it's the first time in your life.
